The contestants on The Voice are in the middle of an intense battle to win the approval of the coaches and the viewers; every performance is a nerve racking do-or-die scenario, but two of next week’s performers aren’t too worried about impressing the coaches, because they are coaches!

Erin Willett, Jermaine Paul, RaeLynn and Jordis Unga, from “Team Blake” will perform with Blake. Christina Aguilera will perform with the remaining members of her team, Ashley De La Rosa, Jesse Campbell, Chris Mann and Lindsey Pavao.

Although they play the part of tense rivals on the hit reality show, Blake told MTV News that he and Christina have developed a real friendship on, and off the set.

“We hang out a little bit. It’s different out there in Los Angeles and I don’t really fit in on the scene, but there’s been a time or two, normally during the live episodes,” he said. “We’ll get together almost every night, all the coaches, believe it or not.”

Blake recalls the first party he and Miranda Lambert threw at their California home, “I had a party last year at my house. And I’ll be damned if the first person at my door wasn’t Christina Aguilera! We love our house parties on The Voice.”

Blake isn’t the only friend Christina’s made on the show. Turns out Xtina will be collaborating with Cee Lo Green on her next album. Recently, she filled fans in on what to expect.

“I’ve been in the studio hard at work. Different producers I’m working with have just excited me so much and given me amazing tracks and beats and material. It’s just filled with fun and excitement,” she said. “[My new album is] going to come out later this year and I’m very, very excited to share it with my fans. Finally.”

Cee Lo Green talked with Billboard about the track they’re working on.

“It’s a song for her album. I won’t disclose the title, because it could possibly be a working title,” he said. “You know, but we’ve talked about it amongst ourselves and I’m gonna go in on it and work it out. It’ll be the second song we’ve done.”
